更新指数体系模型的计算方法 更新指数体系定义为;反映社会经济现象相互联系的指数额群,它满足各因素变动对现象总体影响差额的代数和等于现象总体实际变动差额。差额包括绝对数差和相对数(即指数)差额。 本文以总量指标两因素更新指数体系为例,其模型的计算方法为: The calculation method of the updated index system model The update index system is defined as an index group that reflects the interconnection of social and economic phenomena. It satisfies the algebra of the total impact of each factor change on the phenomenon and equals the actual variation of the overall phenomenon. The difference includes absolute difference and relative (ie index) difference. This article uses the two-factor update index system of total indicators as an example. The calculation method of the model is:
